Starknet v0.14.0: Multi-Sequencer & EIP-1559 Fee Market Live

Published: 2025-08-19 05:39:29 |

Starknet v0.14.0 will launch on mainnet on September 1, 2025. This Layer-2 upgrade deploys a multi-sequencer architecture powered by Tendermint consensus. It aims to enhance censorship resistance, fair transaction ordering and fault tolerance. The update introduces sub-second pre-confirmations, offering near-final transaction feedback within milliseconds while maintaining 4–6 second block times. A new EIP-1559 fee market sets base layer-2 gas fees in FRI (with a minimum of 3 gFRI), decoupling Starknet fees from Ethereum gas volatility. RPC 0.9.0 brings expanded transaction statuses. A redesigned mempool and multi-block processing improve proving efficiency. StarkWare remains in control of sequencers in v0.14.0, but the release marks the first step in a decentralization roadmap to gradually transfer sequencer and prover functions to the community. A brief 15-minute network pause is expected to ensure a smooth migration. Starknet v0.14.0 builds on recent ecosystem milestones, including the Extended DEX rollout, SNIP-31 approval for Bitcoin staking via WBTC and tBTC, and July’s switch to STRK as the sole gas token. Starknet v0.14.0 reinforces Ethereum Layer-2 scalability, decentralization and fee predictability.

Bullish

The v0.14.0 upgrade strengthens Starknet’s core fundamentals by boosting scalability, censorship resistance and fee predictability. Sub-second pre-confirmations and a native EIP-1559 fee market improve the user experience and reduce volatility linked to Ethereum gas. The multi-sequencer architecture under Tendermint consensus marks a clear decentralization roadmap, enhancing long-term network security and community trust. Short-term, traders may see positive price movement around the upgrade event; long-term, improved network throughput and governance should support sustained demand for STRK.
